In the camera test video, Phoenix first appears as Arthur, until he turns into the Joker. The camera pulls in closer and Phoenix is seen smiling and wearing clown makeup, but interestingly not the Joker’s traditional green hair. (Watch the camera test, below.)

He continued: “I think, underneath the excitement of these films, and the size of them, there are these incredible characters that are dealing with real life struggles. And sometimes that is uncovered and exposed, and sometimes it isn’t, and so I always felt, like, there were characters in comics that were really interesting and deserve the opportunity to be kind of studied. And so I think that’s what Todd sees appealing about this idea.”
